The KEEYA’s GN30-12(D) disconnect switch is designed for indoor use with a rated voltage of 12kV and operates on a three-phase AC system at 50/60Hz frequency. Its primary function is to interrupt and transfer current for high-voltage electrical apparatus when they are in a voltage-present but no-load state. This switch is equipped with a rotary moving contact that can be easily installed onto the switchgear, and it also supports wall-through installation. It complies with the standards outlined in IEC62271-102.
1. Altitude: Up to 1000 meters above sea level.
2. Ambient Temperature: Between -25°C and +40°C.
3. Relative Humidity: Daily average not exceeding 95%, and monthly average not surpassing 90%.
4. Seismic Activity: Intensity not exceeding 8 degrees.
5. The designated areas must be free from any inflammable, explosive, corrosive substances, and must not be subject to severe vibrations.
1. Incorporates a well-thought-out design and a pioneering structure.
2. Contact points are strategically distributed on two planes, resulting in minimal operating force and pressure, allowing for easy adjustments.
3. Enhanced components for driving and conducting.
4. Utilizes a column-type moving contact, effectively reducing the required operating force and ensuring a dependable circuit connection.

GN30-12/1250 appearance and installation dimensions
The "GW9-10G" type of outdoor high voltage isolate switch is the high voltage switch equipment of single phase AC 50Hz. The product is suitable for power system with rated voltage 10kV to make or break power supply under circumstances of with voltage and nonload.
The isolator is adopts isolated hook rod to operated.
1.The altitude does not exced 1000m;
2.The ambient air temperature:Maximum +40*C:;Minimum:General Area -30°C.Paramos -40°C;
3.The wind pressure does not exceed 700Pa.(orresponding to 34m/s wind speed):
4.The earthquake intensity does not exceed 8 degrees,
5.The working situstion is without frequent violent vibration;
8.The installation site of ordinary type isolator should be kept sway form g9s, smoke chemical deposition, salt-spray fog. dust
and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.
7.Pollution-proof type isolator is applies to severe filthy conduction ares, however. it shouldn't be any explosive matters and matters causing fire.
